Assistant Professor Marvin Parasram was born and raised in The Bronx, NY.  He received his B.S. in Chemistry from Stony Brook University, his PhD in Chemistry from the University of Illinois at Chicago, and did  NRSA Postdoctoral training at Princeton.  He began his independent career in 2020 at New York University.

Abstract:  Heteroatom units, such as carbonyls, C(sp3)-OH and C(sp3)-NH2 bonds, are prevalent motifs in many medicinal compounds.  Methods to incorporate these important functional groups at the expense of hydrocarbons reply on the use of non-commercial heteroatom transfer agents, precious transition metals, and/or costly engineered enzymes.  Also, these methods often require exogenous oxidants to promote the C-heteroatom bonding event which greatly limits substrate scope. Our laboratory focuses on the employment of economical 1,3-dipoles as versatile reagents that can serve as the hydrocarbon activator and the heteroatom atom source for the heteroatom incorporation of aliphatic systems under benign visible-light irradiation.  Our contributions involve the cleavage of alkenes leading to valuable carbonyl derivatives and the direct C–H oxidation of hydrocarbons via anaerobic oxygen-atom transfer from photoexcited nitroarenes.  Using photoexcited azoxys, an anaerobic nitrogen atom transfer event can occur leading to aziridinatio of alkenes.  Mechanistic studies reveal that the 1.3-dipoles are the sole photo-absorbing species which leads to the formation of diradical intermediates that are responsible for heteroatom transfer events. 
The 71st Annual Undergraduate Research Symposium
to be hosted by Medgar Evers College – CUNY

The Student Activities Committee of the New York Section of the American Chemical Society would like to invite you to attend the 71st Annual Undergraduate Research Symposium (URS) to be held at Medgar Evers College – CUNY  on Saturday May 4, 2024.  This is an in-person symposium of oral presentations.  It provides an excellent opportunity for undergraduate chemistry students in the New York Metropolitan Area to present the results of their research to their peers in a supportive environment. All presentations are oral.  .

Registration is FREE and open to all.   Presenters are asked to register as a 'Student Presenter' and students that wish to attend the event but are not presenting may register as a 'Guest'.
